Abstract

PURPOSE:To produce the titled single crystal having different compositions of the respective layers with excellent productivity, by joining a seed crystal to one end of a specific compound type polycrystalline substance, heating the joined substance and converting the resultant substance into a single crystal in a crystal orientation in which the polycrystal is regulated by the single crystal. CONSTITUTION:A laminated structure containing a starting base material such that the compositions of the respective layers in a stage of forming the starting material are different is fired under temperature condition so as not to homogenize the compositions of the respective layers by mutual diffusion while maintaining the laminated structure. Thereby a compound type polycrystalline substance, capable of wholly exhibiting abnormal grain growth and having different compositions of the respective layers is obtained. A seed single crystalline part 5 is then bonded or joined to at least one end of the resultant polycrystalline substance and the whole is heated to convert the polycrystalline parts 3 and 6 into parts of formed single crystalline part 4 and 7 in a crystal orientation regulated by the single crystals utilizing the abnormal grain growth of the polycrystalline parts 3 and 6.
